The deputy killed in front of the courthouse was attempting to stop him from fleeing. It's not uncommon for a crook to flee before the word gets out. The exit stairwell was apparently right next to the courtroom, and there would have been a bit of a delay before the alarm was raised.

The implied supposition in your question most likely doesn't match the facts in this case.

The deputy shot in front of the courthouse has died now as well? Ugghh.

What a horrible day.

I still can't believe that this guy escaped from a courthouse that would have been crawling with law enforcement officers.
